Collision beam is mu character shape structure, and when colliding, mu character shape structure makes power be transmitted to both ends, although power is dispersed
It is that the power that both ends are subject to is still bigger, to make stringer by biggish power, power is not dispersed effectively, caused to driving
Member and occupant's protecting effect are bad.
Automotive front collision beam energy-absorbing box structure is rushed mainly based on rectangular or tubular box body structure by two U-shapeds at present
Welding manipulator is welded together to form rectangular box like structure energy-absorbing cartridge, and a connecting plate is respectively welded at assembly front and rear portion,
It is connect by connecting plate with anti-collision beam and front longitudinal beam.A kind of vehicle energy absorption box as disclosed in CN103909888 A, the automobile are inhaled
Can box include tubular energy-absorbing box body, energy-absorbing box body one end is equipped with the front mounting plate connecting with automobile buffer beam, another
End is equipped with the rear mounting plate connecting with automobile longitudinal girder, has the crumple groove being recessed inwardly on the energy-absorbing box body side wall.For another example
CN201566701U discloses a kind of front anti-collision beam energy absorbing box, it includes U-shaped box body, and U-shaped box wall is equipped with crumple guiding rib, U
Flask body one end connection plate, the U-shaped box body other end set the connecting plate with front anti-collision beam beam welding, the opening of U-shaped box body
Side connects energy-absorption box plate, and energy-absorption box plate wall is equipped with crumple guiding rib.Although existing energy-absorption box also can effectively by
The power of preceding collision beam is transmitted to stringer, but structure is more complex.
Summary of the invention
The purpose of the utility model is to provide a kind of automotive front collision beam assemblies, when can satisfy vehicle head-on crash
To the intensity requirement of energy-absorption box, collision performance is improved.
Automotive front collision beam assembly described in the utility model, including front beam ontology, two energy-absorption boxes and two companies
Fishplate bar, described two energy-absorption boxes are located at front beam ontology both ends, and energy-absorption box front end is fixedly connected with the trailing flank of front beam ontology,
Rear end is fixedly connected with connecting plate, and the connecting plate is equipped with the installation via hole that connect with stringer, the energy-absorption box be in it is broad in the middle,
Hollow cydariform small in ends.
Further, the material of the energy-absorption box is aluminium alloy.It can be reached on the basis of guaranteeing collision performance using aluminium alloy
To light-weighted purpose.
Further, the front beam ontology includes outer framework and inner support muscle, and the inner support muscle is supported on the forward and backward of outer framework
Between wall.
Further, the upper and lower part of the outer framework is arc-shaped.
Further, the diameter difference of the centre and both ends of the energy-absorption box is 15mm.
Further, the energy-absorption box is equipped with crumple groove, and the trend of the crumple groove and the axis of energy-absorption box are vertical.
The utility model has the following beneficial effects: compared with prior art
1, since energy-absorption box uses drum organization small in the end and big in the middle, crumple deformation requirements are improved, low speed is occurring
When collision, preceding collision beam assembly can reduce crossbeam immersion amount, reduce the damage to cooling system effectively by force dispersion
Degree reduces the maintenance cost of vehicle body, when high velocity impact occurs, can effectively give energy transmission suffered by central collision
Stringer makes deformed area all occur within stringer, ensure that cockpit is indeformable, improves the protecting effect to occupant.
2, since the material of energy-absorption box is that aluminium alloy realizes lightweight, reach under the premise of guaranteeing original collision performance
The purpose for dropping weight cost declining is arrived.
